FRANK JENISON MAIN, OF MADISON, WISOON SIN.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 424,990, dated April 8,1890. 7

Application filed November 23, 1889. Serial Ila-331,294. (N0 model.)

T0 on whom it may concern:

Be it known that I, FRANK J ENISON MAIN, a citizen of the United States,residing at Madison, in the county of Dane and State of WVisconsin, haveinvented certain new and usefullmprovements in Sash-Locks; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

Figure 1 is a front elevation of a portion of a window with my improvedsash-lock applied thereto. Fig. 2 is a vertical section of the same onthe plane of line 1 1. Fig. 3 is a vertical section on the line on m ofFig. 1. Fig. 4 is a top view of the locking-bolt.

The object of my invention is to produce a simple strong automaticlocking-bolt which, in connection with an automatic clasping device,m'ay be readily attached to windowsash.

A is the window-frame.

B and B are the upper and lower sashes.

G is the bottom rail of the upper sash.

D is the center bar of the sash.

D D are panes of glass.

011 the top of the lower sash, and in line with the center bar D of theupper sash, is secured by screws a a the standard E, in which slides aloose locking-bolt F, and from the upper end of which hangs a pendentbolt-keeper G, so as to bear upon the outer end of the sliding bolt F,the standard being perforated near its top at b for the reception of thepivotal end of the pendent boltkeeper and at c for the reception of theloosely-sliding bolt F. The head 6 of this bolt is triangular, as shown,and a triangular recess cl is cut in the front face of the standard Efor its reception.

A keeper fwith an incline on its upper and a shoulder on its lower endand one or more keepers h with inclines at both ends and a recess orsocket between them are secured to the upper sash directly in line withbolt F, as shown in Figs. 1 and 2. The bolt F is long enough to projectunderneath the keeper f or into recess 9 of the keepers h.

To draw the sash together closely at the same time that they areautomatically locked, an upright wedge-shaped tongue of metali issecured to the top of the bottom rail G of the upper sash, and a claspk, with a wedgeshaped open mouth, is secured to the upper rail of thelower sash. When they come together, they hold the sash close togetherlaterally, while the bolting device prevents any Vertical movement.

The pendent bolt-keeper is made in the form shown in the drawings,havinga curved cut-away portion on its inner face Z as a bearing-surfacefor the head of the bolt F, and inwardly-inclined sides next to theexpanding triangular head of the bolt, so as to receive, in connectionwith the bolt, the pressure of the thumb and one finger of the operatorwhen unlocking the bolt or setting the sash.

These devices are supposed to be attached to sash that are suspended andmove freely. When in position, the pendent bolt-keeper is hearingautomatically all the time on the head of the sliding bolt and pressingit against the sash. The automatic operation of the devices takes placeas the sash come together. The pendent keeper allows the bolt 'to slideover the incline of the keeper f on the sash, and after passing forcesit underneath its head, the tongue 11 at the same time being hugged bythe clasp la, and the sash are locked against both side and verticalmovement. There may be one or more of the keepers h secured to the sash,and thus admit of their being locked at any desired height. The bolt,hOW6Y91,Wlll not enter the recesses only when the sash are moved slowly.

It will readily be seen that my device is simple, strong, and easilyapplied to the sides or the center of any window-sash. No springs areneeded, and the locking bolt with its pendentkeeperperformtheirindividual functions separately, and the locking isdone antomatically as the sash are moved into the desired positions.

What I claim as new, and desire to secure bo1t-keeper G, with keepers h,with inclines 10 by Letters Patent, is- I at both ends and interveningsocket, as and 1. An automatic sash-look consisting, of a I for thepurpose set forth. standard E, with a loose sliding bolt F, and Intestimony whereof I ailix my signature in 5 a pendent Weightedbolt-keeper G, attached presence of two Witnesses.

as shown, in combination with keeper f, as FRANK JENISON MAIN. and forthe purpose herein set forth. \Vitnesses:

2. The combination of standard E, provided GEORGE 0. MAIN,

with the loose sliding bolt F and pendent E. S. MCBRIDE.
